How to handle Out of Memory (OOM) in C

Out of memory conditions happen, but what can you do about it? Nothing, abort() your application. What do the so-called memory-safe languages do? They abort(). No, seriously, that pretty much sums it up. I love short blog posts.

Private Cloud Architecture – pt 1

Adventures with Cumulus Linux & Mellanox 100G Switches

We decided to replace our Juniper EX series (in a Virtual Chassis configuration) that had caused us some issues over the last couple of years in 4 separate datacenters.

In researching our needs and our desire to use this as an opportunity to upgrade our backbone (and not just admit we made a bad decision with Juniper), we decided on Mellanox’s Spectrum SN2010 series switches with a mix of 25G and 100G ports in a half-width chassis; Yes, 2 switches per 1U of rack space, each with redundant PSUs. Mellanox has a great reputation in the HPC realm, and are focused on just switches and NICs. To prove out our solution, our vendor, Vology, was able to get us a couple of demo units before shelling out the money for our 8 new switches.
